Title: Deterioration deciding system for magnetic head
Inventor: AYABE SAKAE
IPC: G11B5/09
Filed: 1990-03-06
Abstract: PURPOSE:To prevent working efficiency from falling by writing/reading successively a test signal to/from the track of a disk to be inspected by a magnetic head under the control of a microprocessor, and inspecting a recording meadium by detecting the error of a head signal. CONSTITUTION:Every time a test for S-pieces of the tracks of the disk to be inspected is finished, a reference disk is replaced, and mean read-out voltages V(1), V(2)... for replacement numbers 1, 2... are calculated successively, and is recorded in a memory. If the ratio of the fall of the voltage V is made (k), (k) is calculated by an expression I. The ratio (k) for the number 1, 2,... is either equal to a definite decimal or smaller than it, and it is considered that the performance of the magnetic head falls gradually because of using frequency. This fall is corrected by a correction factor set specially in the microprocessor beforehand. When V(m) falls steeply as shown in a figure, since the ratio (k) for V(m-1) is larger than K, it is decided that the magnetic head is deteriorated, and after the magnetic head is replaced by the good one, the test is started again.

Abstract: PURPOSE:To smooth positioning of a pair of magnetic sensors and to improve copying accuracy by controlling a mechanism for driving said sensors disposed across a welding gap at the speed corresponding to the position of the sensors with respect to the position of a max. leakage magnetic flux. CONSTITUTION:The voltage difference of magnetic signals 104, 106 by sensors 24, 26 supported to a mechanism 28 for driving magnetic sensors is amplified to a differential amplified signal 108 and an amplified signal 110 of the absolute value, which are converted to the pulse signal 112 of the frequency corresponding to said absolute value. On the other hand, a pulse motor 40 is driven respectively in opposite directions by the driving speed signals 100, 102 of AND circuits 44, 46 with the positive and negative of the signal 108 as a comparison signal 114. If the difference in the values detected by the sensors 24, 26 exceeds a prescribed value, the motor 40 is driven at a high speed and if said difference is below the prescribed value, the motor is driven at the low speed corresponding to the difference, by which the sensors are positioned. The sensors are thus quickly and smoothly driven and positioned.

Title: Method for evaluating wear of piston
Inventor: SUDA HIDEO
IPC: G01B11/24
Filed: 1994-02-28
Abstract: PURPOSE:To detect wear of grooves and evaluate its status quantitatively by calculating the position of grooves and converting the calculated position and original image into a unit and waveform data respectively so as to calculate the degree of wear. CONSTITUTION:A piston to be evaluated is mounted on a rotating stage, for example, and the developing picture of outer circumferential surface of the piston is sensed by an optical system and CCD sensor while the piston is rotated, so as to prepare original image data. Then, the position of grooves which is prepared at the time of manufacturing the piston is calculated based on the original image data. That is, the position is estimated from the difference of density in the original image data. Further, the data is converted into a waveform data along an axis crossing the worked groove at a right angle. The waveform data is processed at a unit of width of respective grooves that is calculated from the position of the grooves. In addition, the contact strength for every groove width is calculated based on the waveform data. Since the picture data has various gradations, the contact strength can be calculated based on the difference of its light and darkness.

Abstract: PURPOSE: To obtain satisfactory insulation effect by providing inside of a connecting wick with foam which expands and contracts following changes in temperature of a hot wall so that flow of condensing liquid is stopped.  
     CONSTITUTION: In the air-liquid interface, pressure of control air 25 is higher than the pressure of liquid remaining in a holding tube 17, and surface tension which acts in proportion to curveture of the interface prescribed in connection with structure of wick material, pressure of the control air 25 and pressure of remaining liquid are well equilibrated. In order to maintain foam 24 at the top of a hollow indicator 19, density of a connecting wick 16 is changed in the axial direction of a holding tube 17, and the remaining liquid is also constantly maintained in the holding tube 17. Under such a condition, returning of heat-conveying fluid body from a low-temperature plate 12 to a high-temperature plate 11 is completely dis- turbed, and since an evaporation wick 14 above the high-temperature plate 11 becomes in a dry state, the high-temperature plate 11 is disabled from absorbing heat, and therefore, an insulated state becomes able to be maintained.

Abstract: PURPOSE:To prevent mayonnaise sludge or the like from generating by mixing and finely-pulverizing liquid fuel and water to make these emulsion fuel by means of both the following housing cylindrical face and the serrated edges of the gears wherein a plurality of gears having the diameters specified in the specified relation are housed. CONSTITUTION:The fed fuel and water are successively sent under pressure to the second and third gears 14, 15 from the first gear 13, mixed and finely- pulverized and discharged through an emulsion discharge hole 33 of a force feed part 25 of the third gear 15. Since respective gears have diameters gradually made small for the force feed direction of fuel and water, the fed fuel and water are extremely excellently mixed and finely-pulverized. Furthermore one part of the mixed fuel and water dose not flow back and mayonnaise sludge is not generated as it is called because both the proceeding direction of fuel and water and the rotating direction of the gears are same in the respective clearance parts 26, 27, 28.

Filed: 1985-03-19
Abstract: PURPOSE:To input data to both of a shift circuit constituted by connecting registers in series and a series-parallel shift register consisting of less stages of registers than said circuit in parallel and to take a fault diagnosis easily by providing both circuits. CONSTITUTION:If a fault occurs to one of a data input circuit 13, a data output circuit 14, and shift circuits 31 and 32, data inputted from the data input circuit 13 is not inputted to the shift circuits 31 and 32 correctly and not outputted from the data output circuit 14 correctly either, so it becomes difficult to specifies the fault position. For the purpose, a value set in the series-parallel shift register 1 is inputted to both or either of the shift circuits 31 and 32 selectively, and outputs of the shift circuits 31 and 32 selected through a shift selecting circuit 4 with a selection signal inputted from a terminal 10 are inputted to the series-parallel shift register 1, and outputted to a terminal 9 as serial data, which is confirmed. Consequently, the fault position of the shift circuit 31 or 32 is specified.

Title: Three-input switching circuit
Inventor: USUNAGA AKIRA
IPC: H03K17/62
Filed: 1978-05-06
Abstract: PURPOSE:To make it possible to perform easily switching operation by a single reference signal and two control signals, by using switching circuits and an inhibit circuit. CONSTITUTION:Differential switching circuits 5, 8 and 11 are composed of a couple of identical-conduction type transistors respectively, and inhibit circuit 14 of a couple of identical-conduction type transistors. Further, a constant bias signal (the 3rd control signal) is applied constantly to control signal terminal 25. When the 1st control signal and 2nd control signals are denoted by X and Y, transistor TRs 7, 9 and 13 all conduct with Y greater than Z while other transistors are unconductive, so that the 1st input signal A will appear at output terminal 24. Under a condition of X>Y>Z, applying both X and Y makes TRs 6, 10 and 13 conductive, so that the 2nd input signal B will be outputted from terminal 24. In case of only Z, inhibit circut 14 only conducts to output Z from terminal 24. In this way, an input signal can be switched depending upon the states of control signals X, Y and Z.
